INFORMATION………………………………………… 40 PART NO. 9378945005-04 111 SAFETY PRECAUTIONS •• Be sure to read this Installation manual thoroughly before installation. •• The warnings and precautions indicated in this Installation manual contain important information pertaining to your safety. Be sure to observe them. •• After installing the unit, perform a test run to make sure the unit operates normally. Then, explain to the customer how to operate and maintain the unit. •• Please pass this Installation manual together with the Operating manual to the customer. Please ask the customer to keep the Operating manual and Installation manual at hand for future reference during the moving or repair of the main unit. WARNING! This mark indicates procedures which, if improperly performed, might lead to the death or serious injury of the user. •• Consult the retail store or professional technicians to install the main unit according to the Installation manual. Improper installation will cause serious accidents such as refrigerant leakage, water leakage, electric shock, and fire. Manufacturer's guarantee will be invalid when instructions in the Installation manual are ignored during installation. •• For installation purposes, be sure to use the parts supplied by the manufacturer or other prescribed parts. Using non-specified parts will cause serious accidents such as falling unit, refrigerant leakage, water leakage, electric shock, and fire. •• To install a unit that uses the R410A refrigerant, use dedicated tools and piping materials that have been manufactured specifically for R410A use. Because the pressure of the R410A refrigerant is approximately 1.6 times higher than the R22, failure to use dedicated piping material or improper installation can cause rupture or injury. It will also cause serious accidents such as refrigerant leakage, water leakage, electric shock, and fire. •• Do not introduce any substance other than the prescribed refrigerant into the refrigeration cycle. If air enters the refrigeration cycle, the pressure in the refrigeration cycle will become abnormally high and cause the piping to rupture. •• Be sure to install the unit as prescribed, so that it can withstand earthquakes and typhoons or other strong winds. Improper installation can cause the unit to topple or fall, or other accidents. •• Ensure that the outdoor unit is securely installed at a place that can withstand the weight of the unit. Improper installation will cause injuries caused by falling unit. •• If there is a refrigerant leakage, make sure that it does not exceed the concentration limit. If a refrigerant leakage exceeds the concentration limit, it can lead to accidents such as oxygen starvation. •• If a refrigerant leakage occurs during operation, immediately vacate the premises and thoroughly ventilate the area. If the refrigerant is exposed to fire, it will create a hazardous gas. •• Electrical work must be performed in accordance with this Installation manual by a person certified under the national or regional regulations. Be sure to use a dedicated circuit for the unit. An insufficient power supply circuit or improperly performed electrical work can cause serious accidents such as electric shock or fire. •• For wiring, use the prescribed type of wires, connect them securely, making sure that there are no external forces of the wires applied to the terminal connections. Improperly connected or secured wires can cause serious accidents such as overheating the terminals, electric shock, or fire. •• Securely install the electrical box cover on the unit. An improperly installed electrical box cover can cause serious accidents such as electric shock or fire through exposure to dust or water. •• Do not turn ON the power until all work has been completed. Turning ON the power before the work is completed can cause serious accidents such as electric shock or fire. •• After the installation, make sure there is no refrigerant leakage. If the refrigerant leaks into the room and becomes exposed to a source of fire such as a fan heater, stove, or burner, it will create a hazardous gas. •• Use a wall hole pipe. Otherwise, it may cause a short circuit. En-2 •• Do not place the outdoor unit near the handrail of the balcony. Children may climb onto the outdoor unit, lean over the handrail and fall over. •• Use only a specified power cable.Poor connection, poor insulation, and exceeding the allowable current will lead to electric shock and fire. •• Attach the connecting cables securely to the terminal. Or secure it firmly with a "wiring suppressor". Loose connection will lead to malfunction, electric shock, and fire. English •• Install a breaker(earth leakage breaker) to cut off all AC main current at the same time. If you do not install a breaker (earth leakage breaker), it may cause electric shock and fire. •• Be sure to install the refrigerant pipe before operating the compressor. If the refrigerant pipe is not installed and you operate the compressor while the valve is open, air will be sucked into the system and abnormal pressure will occur in the cooling cycle. This will damage the unit and cause injuries. CAUTION! This mark indicates procedures which, if improperly performed, might possibly result in personal harm to the user, or damage to property. •• Do not install the unit in the following areas: •• Area with high salt content, such as at the seaside. It will deteriorate metal parts, causing the parts to fall or the unit to leak water. •• Area filled with mineral oil or containing a large amount of splashed oil or steam, such as a kitchen. It will deteriorate plastic parts, causing the parts to fall or the unit to leak water. •• Area that generates substances that adversely affect the equipment, such as sulfuric gas, chlorine gas, acid, or alkali. It will cause the copper pipes and brazed joints to corrode, which can cause refrigerant leakage. •• Area containing equipment that generates electromagnetic interference. It will cause the control system to malfunction, preventing the unit from operating normally. •• Area that can cause combustible gas to leak, contains suspended carbon fibers or flammable dust, or volatile inflammables such as paint thinner or gasoline. If gas leaks and settles around the unit, it can cause a fire. •• Avoid installing the unit at places where it will come into contact with animals’ urine or ammonia. •• Do not use the unit for special purposes, such as storing food, raising animals, growing plants, or preserving precision devices or art objects. It can degrade the quality of the preserved or stored objects. •• Ground the unit. Do not connect the ground wire to a gas pipe, water pipe, lightning rod, or a telephone ground wire. Improper grounding may cause electric shock. •• Perform draining for the unit according to the Installation manual. Check that the water is properly drained. If the drain processing is improperly installed, water may drip down from the unit, wetting the furniture. •• Do not touch the fins with bare hands. Regulation •• This unit must be connected to a power supply with impedance of 0.33 ohm and below.If the power supply does not satisfy this requirement, please consult the power supplier. •• This product is intended for professional use. Be sure to use a dedicated power circuit. Never use a power supply shared by another appliance. En-3 222 ABOUT THE PRODUCT 222222 Caution when using R410A refrigerant Pay careful attention to the following points : •• Since the working pressure is 1.6 times higher than that of R22 models, some of the piping and installation and service tools are special. (See the table in the SPECIAL TOOLS FOR R410A section.) Especially, when replacing a conventional refrigerant (other than R410A) model with a new refrigerant R410A model, always replace the conventional piping and flare nuts with the R410A piping and flare nuts. •• Models that use refrigerant R410A have a different charging port thread diameter to prevent erroneous charging with R22, R407C and for safety. Therefore, check beforehand. [The charging port thread diameter for R410A is 1/2 UNF 20 threads per inch.] •• Be more careful than the installation of the refrigerant (other than R410A) models, not to enter foreign matters (oil, water, etc.) and other refrigerant into the piping. Also, when storing the piping, securely seal the openings by pinching, taping, etc. •• When charging the refrigerant, take into account the slight change in the composition of the gas and liquid phases, and always charge from the liquid phase side whose composition is stable. 222222 Special tools for R410A Tool name Contents of change for R22 tool Gauge manifold Pressure is huge and cannot be measured with a conventional gauge. To prevent erroneous mixing of other refrigerants, the diameter of each port has been changed. It is recommended to use a gauge manifold with a high pressure display range -0.1 to 5.3 MPa and a low pressure display range -0.1 to 3.8 MPa. Charging hose To increase pressure resistance, the hose material and base size were changed. Vacuum pump A conventional vacuum pump can be used by installing a vacuum pump adapter. Gas leakage detector Special gas leakage detector for HFC refrigerant R410A. 222222 Accessories Use connecting parts as required.

Nitrogen gas pressure: 0.02 MPa (= pressure felt sufficiently on the back of your hand) English •• If air or another type of refrigerant enters the refrigeration cycle, the internal pressure in the refrigeration cycle will become abnormally high and prevent the unit from exerting its full performance. Nitrogen gas Brazing area •• If a pipe is brazed without applying nitrogen gas, it will create an oxidation film. This can degrade performance or damage the parts in the unit (such as the compressor or valves). •• Do not use flux to braze pipes. If the flux is the chlorine type, it will cause the pipes to corrode. In addition, if the flux contains fluoride, it will affect the refrigerant piping system due to deterioration of refrigerant oil. •• For brazing material, use phosphor copper that does not require flux. 555555 Indoor unit pipe connections CAUTION Separation tube B Horizontal A B Vertical A or Horizontal line ±15°C NO GOOD OK B A A : Outdoor unit or Refrigerant branch kit B : Indoor unit or Refrigerant branch kit Header Gas pipe Outdoor unit side Horizontal line C H1 Horizontal (A1 : 0o – 1o) line B1: -10o – 10o VIEW C A1 Horizontal Horizontal line line Liquid pipe Outdoor unit side H1 = 0 mm – 10 mm B1 D H2 A2 B2 OK Main pipe VIEW D 0.5m or more To indoor unit Main pipe 0.5m or more To indoor unit Separation tube or Header H2 = 0 mm – 10 mm (A2 : 0o – 1o) B2: -10o – 10o To indoor unit NO GOOD Separation tube 0.5m or more To indoor unit or Header 0.5m or more To indoor unit NO GOOD To indoor unit •• Do not connect a separation tube after a header. •• Leave the distance 0.5 m or more for straight part to branch tube and header. •• For details, refer to the Installation Instruction Sheet of each part.
